Abstract: A process and device for assisting aerial navigation. The system affords the pilot of the aircraft greater knowledge regarding the situation which results from automatic decisions of a flight management system. A central zone is displayed on a viewing screen which represents the overall use of the navigation instruments. Peripheral zones of the screen represent the individual instruments with a visible plot of the relationship between the central zone and a particular peripheral zone when the latter corresponds to a navigation instrument actually being used. For example, the central zone is a disk whose diameter represents the mean error in position given by the use of the various instruments and the visible plots of relationship are color radial sectors which extend between the central zone and certain peripheral zones. The names of the instruments are indicated in the peripheral zones.

Abstract: Process and device using a flight management system (FMS) for aiding aerial navigation. To facilitate the task of the pilot, the FMS carries out a dialogue with the pilot via a data display and input console (MCDU), which displays a list of tasks to be executed in the form of a succession of selectable and activatable main zones. Each zone corresponds to a task, executed via the console, and when the task has been executed (validation key actuated by the pilot), the list of tasks is redisplayed, with the zones for which tasks have been executed and validated appearing in a different color from other zones. The zones preferably appear in duplicate when there is a co-pilot, so that it is easy to see which tasks have been performed and by which pilot, and which tasks remain to be performed.

Abstract: The invention relates to processes for aiding aerial navigation. According to the invention, there is proposed a process for aiding aerial navigation, using a flight management system (FMS) which carriers out a dialogue with the pilot by means of several interfaces which include at least one display screen. The flight management system displays on the screen a time-graduated abscissa axis, an altitude-graduated ordinate axis, and, in this system of axes, a plot representing a theoretical path of an aircraft. The flight management system scrolls the time axis and optionally the altitude axis in such a way that the origin of the axes at the instant of display represents, along the abscissa, the time at the instant of display and along the ordinate the altitude of the aircraft at this instant. The pilot thus obtains a better assessment of the time management of the flight.

Abstract: To facilitate the task of a pilot, an on-board computer (FMS) carries out a dialogue with the pilot via a data display and input console (MCDU). This console displays a list of tasks to be executed in the form of a succession of selectable and activatable main zones (40). Each zone corresponds to a task, executed via the console, and when the task has been executed (validation key actuated by the pilot), the list of tasks is redisplayed with a specific mark in an auxiliary zone (50) corresponding to the task executed. The auxiliary zone is located next to the main zone in which the task to be performed appears. The copilot, if there is one, receives the same mark. If it is he who executes the procedure, the mark appears in another auxiliary zone (60) lying on the other side of the main zone. At any instant of the procedure, the pilot and the copilot both see at a glance which tasks have been executed, who has executed each, and which tasks remain to be performed.
